Yahoo mail not sending from Droid

I setup the Yahoo mail when I got my Droid last month. I am having an issue where the emails I compose on the Droid are not being sent, but are just sitting in the "Outbox" and not going in my "Sent Mail."

I followed these directions to setup up Yahoo on my Droid:

To set up Yahoo E-Mail on the Motorola Droid:

Make sure Wi-Fi is turned off

Press the E-Mail icon (the default Android E-Mail application)

Enter your Yahoo E-Mail address and password

Press “Manual Setup” in the lower left hand corner

For “Incoming Server Settings” set the IMAP server to “imap.mail.yahoo.com” and the Port to 143

For “Outgoing Server Settings” set the SMTP Server to “smtp.mobile.mail.yahoo.com” and the Port to 587

Check “Require sign-in” and press Next

Select how often your Droid will check for Email, and choose default options

Give the account a name and set your display name for outgoing messages

Any thoughts on what I can do? Should I use a different server for sending emails? I can send emails just fine from my Gmail account. Thanks in advance!

I had the same issue and realized that instead of deleting and reentering the smpt.mobile.mail.yahoo.com, I only modified this field from the original setting. Try deleting and re-typing smpt.mobile.mail.yahoo.com, this should work out for you...good luck

I think you can try omitting the "mobile" from the outgoing server settings, i.e. "smtp.mail.yahoo.com", but I'm not sure why the original setting isn't working for you. It's the same one I used, and mine has worked mostly fine for me.

For those who are having issues successfully SENDING Yahoo! Mail E-Mail from their natively installed Android OS Email app but who are receiving E-Mail just fine in the same app, I recommend doing the following:

Going into Settings > Accounts and Sync and changing the status of Background Data (if it is on, switch it off, and if it is off, switch it on.

If that does not allow you to send, in the Email app, tap Menu > More > Account Settings > Outgoing Settings and ensure that the Outgoing Server Settings read as follows:

smtp.mail.yahoo.com
SSL
465

Of course, also check Require Sign In and provide your Yahoo! Mail credentials. You can also try adding and/or removing the User Name suffix as well (i.e. @yahoo.com)

This is the screen that will confirm if you will be able to successfully send E-Mail or not from within the native Android OS Email app, in that if you receive the message:

Setup could not finish
Cannot safely connect to server. ( java.security.cert.CertPathValidatorException: Trust anchor for the certification path not found.)

then your E-Mail will not successfully send from the native Android OS Email app. However, if upon applying the settings in Menu > More > Account Settings > Outgoing Settings, the settings simply apply, then you will have a small window where you WILL be able to send E-Mail from the native Android OS Email app (be forewarned, this window lasted 2-3 messages for me, upon which point the error then returned.)

I've also had luck getting these settings to stick through simultaneously opening the native Android OS web browser and logging on to mail.yahoo.com through there. For some reason, accessing my E-Mail through the web browser followed by then trying to apply the settings in the native Android OS Email app (Menu > More > Account Settings > Outgoing Settings) permitted another small window in which I could send E-Mail from the native Android OS Email app.

My plan of attack through all of this is to read E-Mail using my native Android OS Email app (the sorting options are far richer than the web browser version AND the official Yahoo! Mail app) and to compose E-Mail using the web browser version.

Note that I am currently a Yahoo! Mail Classic user (and will remain one until Yahoo! forces me to change)
